RIFLE-SIGHT.

To all whom it may concern:

Be it known that I, GLENN R. HATHAWAY, a citizen of the United States,residing at Detroit, in the county of WVayne and State of Michigan, haveinvent-ed new and useful Improvements in Rifle-Sights, of which thefollowing is a specification.

The invention relates to sights for fire arms, and more particularly tothe class of adjustable sights for rifles.

The primary object of the invention is the provision of a sight of thischaracter in which there is arranged a rotatable cylinder provided witha bar and V-sha-ped notch adapted to be alternately brought into properposition for the vision in aiming a rifle, the aforesaid bar takingadvantage of the fact that the eye cannot focus on two objects at thesame time that are not the same distance from the eye, the bead of thefront sight being plainly visible therethrough, thus enabling a true andaccurate aim upon an object at all times when desiring to bring therifle into action.

Another object of the invention is the provision of a sight in which theV-shaped sight opening and the cross bar sight will be shielded, so asto destroy the dazzle and blur common when sighting a rifle, or otherfire arms.

A further object of the invention is the provision of a sight in whichthe same may be vertically adjusted to the required height for firingrelatively long distances.

A still further object of the invention is the provision of a sight ofthis character which is simple in construction, readily and easilyadjusted, and that is thoroughly reliable and efficient in operation,and inexpensive in manufacture.

ith these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a fragmentary side elevation of a riflebarrel, showing the sight thereon constructed in accordance with theinvention. Fig. 2 is a top plan Specification of Letters Patent.

view thereof. Fig. 3 is a front elevation, showing the adjustablecylinder in one position. Fig. 4e is a rear elevation, showing thecylinder adjusted in another position. Fig. 5 is a fragmentary sideelevation of the sight shown in raised position. Fig. 6 is a fragmentarybottom plan view of the sight removed from the rifle barrel. Fig. 7 is aperspective view of the locking dog removed from the sight. Fig. 8 is avertical longitudinal sectional view through the sight and rifle barrel.Fig. 9 is a transverse sectional view on the line 99 of Fig. 1. Fig. 10is a further fragmentary vertical sectional view through the riflesight, showing in detail the manner of locking the cylinder.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring to the drawings by numerals, 5 designates generally a riflebarrel which may be of any ordinary well-known type, and upon which aremounted the front and rear sights designated by the numerals 6 and 7,respectively. The front sight is provided with the usual bead 8, whichis visible through the rear sight, presently described. The rear sightis arranged at the breech end of the rifle barrel, as usual, andcomprises a flat spring shank 9, the same being formed on the lower faceof its forward end with a transverse undercut lug 10, which is insertedin a corresponding slot 11 in the top of the rifle barrel 5 for themounting of the shank thereon. Formed at the rear end of the shank 9 isan upwardly extending cylindrical-shaped casing or housing 12, the samebeing elevated above the plane of the shank and formed with a medial cutaway portion 13, the bottom thereof being rounded, as at 14, and whichis designed for a vision gap in the casing or housing in alinement withthe front sight.

Mounted within the casing or housing is a rotatable cylinder 15, thesame being formed at opposite ends with heads 16 which frictionallyengage the ends of the casing or housing 12 and prevent the lateraldisplacement of the said cylinder therein, when the same is beingrotated. This cylinder 15 is medially cut away to form a V-shaped sightnotch 17 at one side thereof, and a cross sight bar 18 at the oppositeside, diametrically opposed to the V-shaped sight notch, so that uponrotation of the cylinder 15 within the casing or housing 12, theV-shaped notch 17 may be brought into proper focus with the bead uponthe forward sight, and on the turning of the cylinder in the reversedirection, the cross sight bar 18 may be brought into focus with respectto the said bead on the forward Sight. The medial cut away portion inthe cylinder 15 extends below the cross sight bar 18 to form asemi-circular shaped opening 19, so that the whole of the forward sightmay be made visible at all times, as well as the object aimed at.

Fixed to one end of the cylinder 15 is an outwardly bowed compressibleleaf spring catch 20, one end of which is left free, and is formed withan upturned locking lip 21 adapted to engage in either of a pair ofspaced notches 22 formed in one side wall of the cut away portion in thehousing or casing 12 for locking the said cylinder in adjusted positiontherein, so that the V-shaped sight notch 17 or the cross sight bar 18will be held in locked adjusted position for presentation to the eye ofthe user of the rifle for the sighting thereof. Thus, it will be seenthat the user of the rifle will have the benefit and advantages of twoindependent sights, namely, the horizontal cross sight bar 18', and theV-shaped sight notch 17 formed in the cylinder on the adjustmentthereof.

Formed in the shank 9, forwardly of the housing or casing 12, inopposite side edges thereof, are notches 23, and also formed medially ofthe said shank between the notches is an elongated slot 24, into whichprojects the leg 25 of a locking member which is formed with upturnedlocking dogs 26, the same extending through the notches 23 and adaptedto engage in cross cuts forming corrugations 27 in one side of thehousing or casing 12 for elevating the sighting cylinder the requireddistance from the rifle barrel, the leg being forwardly inclined andcontacting with the top of the rifle barrel, when the cylinder has beenelevated, and the sight in this instance is used for visually focusingobjects at different distances. It will thus be seen that the sight maybe vertically adjusted and locked in such position by the lockingmember. This locking member is formed with forwardly extending fingergrips 28, the latter being formed on and projecting at right angles fromthe locking dogs 26, so that by manually gripping the same, the lockingmember may be engaged with the corrugations or disengaged therefrom,thus permitting the sight cylinder to be raised and locked in suchposition as shown in Figs. 5, 8 and 10 of the drawings, by reason ofsaid dog 26 looking with the corrugations in the housing and the legresting on the barrel, or brought to lowered position upon the riflebarrel. It will be noted that the sight notches 17 and 18 will beshielded by the heads 16 on the ends of the cylinder 15, and also thecasing or housing 12, so as to avoid the blurring of the notch common insights.

The housing 12 is cut into at its under side to provide a spring finger29 formed with an inturned nib 30 which is adapted to engage any one ofa series of notches 31 formed in the cylinder 15, so as to hold the saidcylinder rigidly in place for using the sight in shooting. Thecorrugations 31 are arranged in close relation to each other, so as toenable a very accurate height adjustment to be had. When the nib of thespring linger 29 engagesin one of the notches, it will be apparent thatthe cylinder will be held locked, so that there will be no possibilityof the turning of the cylinder in the housing to alter the adjustment ofthe sight.

From the foregoing, taken in connection with the accompanying drawings,it is thought that the construction and operation of the invention willbe readily understood, without requiring a more extended explanation.
